In 2000, a number of libraries within the University of Oxford were brought together for administrative purposes under the aegis of what was initially known as Oxford University Library Services (OULS), and since 2010 as the Bodleian Libraries, of which the Bodleian is the largest component.

The Bodleian Library occupies a group of five buildings near Broad Street: these range in date from the late medieval Duke Humfrey's Library to the New Bodleian of the 1930s. Since the 19th century a number of underground stores have been built below parts of these.

Before being granted access to the library, new readers are required to agree to a formal declaration. This declaration was traditionally oral, but is now usually made by signing a letter to the same effect. Ceremonies in which readers recite the declaration are still performed for those who wish to take them; these occur primarily at the start of the University's Michaelmas term. External readers (those not attached to the University) are still required to recite the declaration orally prior to admission. The Bodleian Admissions Office has amassed a large collection of translations of the declaration allowing those who are not native English speakers to recite it in their first language. The English text of the declaration is as follows:

I hereby undertake not to remove from the Library, nor to mark, deface, or injure in any way, any volume, document or other object belonging to it or in its custody; not to bring into the Library, or kindle therein, any fire or flame, and not to smoke in the Library; and I promise to obey all rules of the Library.

This is a translation of the traditional Latin oath (the original version of which did not forbid tobacco smoking, though libraries were then unheated because fires were so hazardous):

The late sixteenth century saw the library go through a period of decline: the library’s furniture was sold, and only three of the original books belonging to Duke Humfrey remained in the collection.[8] It was not until 1598 that the library began to thrive once more, when Thomas Bodley (a former fellow of Merton College) wrote to the Vice Chancellor of the University offering to support the development of the library: "where there hath bin hertofore a publike library in Oxford: which you know is apparent by the rome it self remayning, and by your statute records I will take the charge and cost upon me, to reduce it again to his former use."[9] Duke Humfrey’s Library was refitted, and Bodley donated a number of his own books to furnish it. The library was formally re-opened on 8 November 1602 under the name “Bodleian Library” (officially Bodley's Library).[8]

Bodley’s collecting interests were varied; according to the library's historian Ian Philip, as early as June 1603 he was attempting to source manuscripts from Turkey, and it was during “the same year that the first Chinese book was acquired.”[10] In 1610, Bodley made an agreement with the Stationers' Company in London to put a copy of every book registered with them in the library. The Bodleian collection grew so fast that the building was expanded between 1610–1612, (known as the Arts End) and again in 1634–1637. When John Selden died in 1654, he left the Bodleian his large collection of books and manuscripts. The later addition to Duke Humfrey’s Library continues to be known as the "Selden End".

By the time of Bodley’s death in 1612, further expansion to the library was being planned. The Schools Quadrangle (sometimes referred to as the "Old Schools Quadrangle", or the "Old Library") was built between 1613 and 1619 by adding three wings to the Proscholium and Arts End. Its tower forms the main entrance to the library, and is known as the Tower of the Five Orders. The Tower is so named because it is ornamented, in ascending order, with the columns of each of the five orders of classical architecture: Tuscan, Doric, Ionic, Corinthian and Composite.

The three wings of the quadrangle have three floors: rooms on the ground and upper floors of the quadrangle (excluding Duke Humfrey’s library, above the Divinity School) were originally used as lecture space and an art gallery. The lecture rooms are still indicated by the inscriptions over the doors (see illustration). As the library’s collections expanded, these rooms were gradually taken over, the University lectures and examinations were moved into the a newly created University Schools building. The art collection was transferred to the Ashmolean. One of the schools is now used to host exhibitions of the library’s treasures, whilst the others are used as offices and meeting rooms for the library administrators.

The agreement with the Stationers' Company meant that the growth of stock was constant and there were also a number of large bequests and acquisitions for other reasons. Until the establishment of the British Museum in 1753 the Bodleian was effectively the national library of England. By then the Bodleian, Cambridge University Library and the Royal Library were the most extensive book collections in England and Wales.

By the late 18th century, further growth of the library demanded more expansion space. In 1860, the library was allowed to take over the adjacent building, known as the Radcliffe Camera. In 1861, the library’s medical and scientific collections were transferred to the Radcliffe Science Library, which had been built farther north next to the University Museum.

The Clarendon Building was designed by Nicholas Hawksmoor and was built between 1711 and 1715, originally to house the printing presses of the Oxford University Press. It was vacated by the Press in the early nineteenth century, and used by the university for administrative purposes. In 1975 it was handed over to the Bodleian Library, and now provides office and meeting space for senior members of staff.[12]

Between 1909 and 1912, an underground bookstack was constructed beneath the Radcliffe Camera and Radcliffe Square.[14] In 1914, the total number of books in the library’s collections breached the 1 million mark.[14] By the 1920s, the Library needed further expansion space, and in 1937 building work began on the New Bodleian building, opposite the Clarendon Building on the north-east corner of Broad Street.

The New Bodleian was designed by architect Sir Giles Gilbert Scott. Construction was completed in 1940. The building was of an innovative ziggurat design, with 60% of the bookstack below ground level.[15][16] A tunnel under Broad Street connects the Old and New Bodleian buildings, and contains a pedestrian walkway, a mechanical book conveyor and a pneumatic Lamson tube system which was used for book orders until an electronic automated stack request system was introduced in 2002.[17] The Lamson tube system continued to be used by readers requesting manuscripts to be delivered to Duke Humfrey’s Library until it was turned off in July 2009. In 2010, it was announced that the conveyor, which had been transporting books under Broad Street since the 1940s, would be shut down and dismantled on 20 August 2010.[18][19] The New Bodleian closed on 29 July 2011.[citation needed]

The New Bodleian building was rebuilt behind its original façade to provide improved storage facilities for rare and fragile material, as well as better facilities for readers and visitors.[20] It reopened to readers as the Weston Library on 21 March 2015.[21] In March 2010 the group of libraries known collectively as "Oxford University Library Services" was renamed "The Bodleian Libraries", thus allowing those Oxford members outside the Bodleian to acquire the gloss of the Bodleian brand.[22]

The library operates a strict policy on copying of material. Until fairly recently, personal photocopying of library material was not permitted, as there was concern that copying and excessive handling would result in damage. However individuals may now copy most material produced after 1900, and a staff-mediated service is provided for certain types of material dated between 1801 and 1900. Handheld scanners and digital cameras are also permitted for use on most post-1900 publications and digital cameras may also be used, with permission, with older material.[23] The Library will supply digital scans of most pre-1801 material. Microform copies have been made of many of the most fragile items in the library's collection, and these are substituted for the originals whenever possible. The library has a close relationship with the Oxford Digital Library, which is in the process of digitising some of the many rare and unusual items in the University's collection.

The head of the Bodleian Library is known as "Bodley's Librarian". The first librarian, Thomas James, was selected by Bodley in 1599, and the university confirmed James in his post in 1602.[26][27] Bodley wanted his librarian to be "some one that is noted and known for a diligent Student, and in all his conversation to be trusty, active, and discreet, a graduate also and a Linguist, not encumbered with marriage, nor with a benefice of Cure",[28] although James was able to persuade Bodley to let him get married and to become Rector of St Aldate's Church, Oxford.[27]

In all, 24 have served as Bodley's Librarian; their levels of diligence have varied over the years. Thomas Lockey (1660–1665) was regarded as not fit for the post,[29]John Hudson (1701–1719) has been described as "negligent if not incapable",[30] and John Price (1768–1813) was accused by a contemporary scholar of "a regular and constant neglect of his duty".[31] The last Librarian, Sarah Thomas, served from 2007 to 2013; she was the first woman to hold the position, and the second Librarian (after her predecessor, Reginald Carr) also to be Director of Oxford University Library Services (now Bodleian Libraries). Thomas, an American, was also the first foreign librarian to run the Bodleian.[32] Her successor from January 2014 is Richard Ovenden, who was Deputy Librarian under Thomas.

Historian and novelist Deborah Harkness, set much of the early part of her 2011 novel, A Discovery of Witches, in the Bodleian, particularly the Selden End. The novel also features one of the library's Ashmolean manuscripts (Ashmole 782) as a central element of the book.

The Library's fine architecture has made it a favourite location for filmmakers, representing either Oxford University or other locations. It can be seen in the opening scene of The Golden Compass, Brideshead Revisited (1981 TV serial), Another Country (1984), The Madness of King George III (1994), and the first two Harry Potter films, in which the Divinity School doubles as the Hogwarts hospital wing and Duke Humfrey's Library as the Hogwarts library.[33] In The New World (2005), the library edifice is portrayed as the entrance to the Royal Court of the English monarchy. The Bodleian also featured in the Inspector Morse televised spin off Lewis, in the episode "And the Moonbeams Kiss the Sea", where a murder takes place in the basement. It also featured in the episode "Fugue" of the Inspector Morse televised spin off Endeavour as the answer to an anagrammatic clue left by a serial killer for the young Morse.
